'Ihe' )resent invention relates to a framin g V measurement may be takenfor a bra'ce l-n a tool, and bevel protractor; and has for its principalobject to provide a structure of. corner, e 7 this nature which iseiilcientqm enabling one Figure 7 18 a transverse section taken sub! toobtain the angle of bevel for each end and at the same time obtain thelength'of any brace, rafter purline, beam, strut, or the like, byadjusting the tool to the actual position of the proposed brace, etc.then trans 19 ferring the tool to the stick from. which the brace, etc.is to be cut by placing the tool on the stick and scribing,orjmarking-acrossthe ends. 7 Another important object of 'tlieinventionis to provide protractor headsrwhich may be adjusted'inone plane forplain work or may be adjusted in twio planes, 'orboth directions', forthe purpose of marking jack rafters, hip and valley. rafters, obliquebraces,,or braces which are to fit inbetween timbers that are warped,crooked, or twisted. Another object of the invention is to provide aspecial attachment with adjustable wings to replace one of theprotractors for the purpose o'f marking braces to fit in corners, of anyangle, acute or obtuse.

. Another important object of the invention is to provide a tool of thisnature which is exceedingly simple in construction, easy to manipulateand adjust, reliable and efficient in use, not likely-to easily becomeout of .order, and otherwise well adapted to the purpose for which it isdesigned.

With the above and numerous other ob jects in view as will appear as the'description proceeds, the invention resides in certain novel featuresof construction, and in the combination and arrangement of parts as willbe'hereinafter more fully described and claimed. In the drawing:- aFigure'l is an elevation of the tool show ing the same used to take themeasurementsfor a proposed brace between two angularly disposed members,4

Figure 2 is a similar view showing the same applied to the stick fromwhich the brace is to be cut,

. Referring totlie drawing in detail it-will be seen that the shank ofthe tool includes a I pair-of rods "5' and6, one of which has a bolt 7projected therethrough which extends through an elongated slot 8provided in the other member. nut (not shown) associated therewithwhereby the members 5 and 6 may be held in different adjusted positionsin respect to each other so as to vary the length of the shank as may bedesired. 'Itis preferable to'con struct the member -6 withlongitudinally extending rectangularly disposed edge-flanges i0in'between which received the-memer. 5. ijrnprotractor headll ispivotedon :the end ofthe member '6 by means ofa bolt 12 which'm-ay be tightenedforholding the head 11 at different angles in respect to'the-shank.Another protractor'head 13 is pivoted on the end of the member 5 bymeans o'fa bolt 14: which mavbe tightened bymeans of the nut 15'. Theprotractor head 13is provided with pin extensions l5 disposed inopposite directions which rotatably'receive thesleeves 16*of a.astraiiglrt eclgegplate 1 7.1 Thus the plate 17 may be rotated indifferenta ngljes;

in respect'to the head 13. A bolt 18 passes transversely through one ofthe sleeves 16" as is clearly shown in Figure 5, and the head thereof isrested in a seat 19 so as to frictionally engage the adjacentpin 15, sothat by tightening'up on the nut 20, the bolt head 18 will bind intoengagement with the pin-15, and hold the plate 17 at any desiredadjusted angle.

y removing the bolt 14, the head 13 may be removed from the shank, and aprotractor indicated generally by the letter A may be substitutedtherefor as is indicated in Figure (3. Referring particularly to thisprotractor A, itwill be seen that the numeral 22 indicates a shank whichis provided with right angularly disposed flanges 23 at its longitudinaledges for straddling the shank, and particularly the member 5 thereof asis This bolt 7 hasa suitable clearly indicated in Figure 7', so thatwhen the bolt 14 is placed through the opening in the member 5, andthrough the shank 22, said shank 22 is held in fixed alignment with themember 5. The shank 22 is provided with an elongated slot 24- cxtendinglongitudinally thereof. A pair of straight edge wings 25 are pivoted tothe end of the shank 22as at 26. Links 27 are pivoted adjacent the'endsof the wings 25, and are provided with elongated slots 28 so that a bolt29 may be passed therethrough and through the slot 24, so that when thenut thereof is loosened, the Wings 25 may be adjusted to differentangles in respect to each other, depending upon the angle of the corner,such as is indi cated in Figure 6, and then the nut tightened, and thusthe wings are held in this angle.

It is thought that'one example of the use of the tool will be sufficientto set forth its utility to those skilled in the carpenter art. As shownin Figure 1. the tool is placed in the exact position of the proposedbrace or strut. The tool is then taken away and placed on the stick asis shown in Figure 2, so

i that by scribing along the straight edges of the protractors 11 and13, the stick may be cut so as to form the brace or strut fortitting inthe position of the tool as it is shown in Figure 1. 7 The adjustabilityof the plate 17 in relation to the protractor head 13 takes care of anybevel whichmay be provided in one of the members, and thus by placingthe tool on both sides of the stick, this bevel may be cut on the braceor strut. The device is used in the same manner in connec tion with acorner as shown in Figure 6, eX- cept that the protractor 13 is takenoff, and the protractor A substituted therefor.

With reference particularly to the straight edge 30 shown in Figures 8and 9, it is desired to point out that the lower end of a jackrafterfits on the wall plate of a building, while the upper end of a jackrafter fits in the hip rafters. Also, the lower end of a jack rafter isat right angles to the wall plate, while the upper end of a jack rafteris at an angle with the hip rafter, both vertically and horizontally;therefore, while the.

able fastening device which may be passed through one of the slots 32'.

It 1s thought that the construction, utility, operatlon, and advantagesof the invention wil now be clearly understood by those skilled in thisart. The present embodi ments of the invention havebeen disclosed merelyby way of example, and in practice attains the various features 7 ofadvantage enumerated as desirable in the statement of the invention, andthe above description. It will be apparent, however, that numerouschanges in the details of construction, and in the combination andarrangement of parts may be resorted to without departing from thespirit or scope of the invention as herein after claimed or sacrificingany of its advantages.

Having thus described the invention, what I claim'as new and desire tosecure by Letters Patent is w A tool of the class described including anadjustable shanks, heads pivoted on the shank, means for holding theheads at different angles to said shank, a plate, means for rotatablymounting the plate on one of said heads, and means for holding thepl-ate'at different angles in relation to said last mentioned head, theaxis of rotation of the platebeing in a plane at a right angle to theaxis of rotation of the head on which said plate is mounted.

In testimony whereof I affix my signature.
